Product Description
Shimano 10CCV Pressure Plate Spring (TT0518)
The Shimano 10CCV Pressure Plate Spring (TT0518) is a specialized tension component essential for the proper functioning of the lever drag system in Shimano offshore reels. This spring is located within the drag stack and is responsible for providing the outward "return" pressure against the pressure plate.
When you move the drag lever from "Strike" or "Full" back to the "Free" position, this spring ensures that the pressure plate and drag washers disengage completely from the spool. Without a high-tension spring like the 10CCV, the drag might "drag" or fail to enter a true free-spool state, which is critical for dropping baits or casting. Replacing a weakened or corroded spring restores the crisp, mechanical separation required for elite-level offshore performance.

Compatibility & Fitment
The 10CCV (TT0518) is a heavy-duty component designed for Shimano’s larger-capacity lever drag reels. It is a direct factory fit for the following series:
-
Shimano Tiagra Series: TI-12, TI-16, TI-20, TI-30, TI-30W, TI-50, TI-50W, TI-50WA, TI-80W, TI-130A
-
Shimano Tyrnos Series: Select high-capacity 2-Speed models (Verify via TT code)
-
Shimano TLD Series: TLD-20II, TLD-30II, TLD-50II
Pro Tip: During a drag service, the pressure plate spring should be inspected for any signs of "pancake" compression (loss of height). If the spring has lost its arc, your free-spool will suffer. When reassembling, ensure the spring is seated perfectly centered to avoid uneven pressure on the drag plate.

Key Features
-
High-Memory Alloy: Engineered to maintain its "push" even after being compressed under hundreds of pounds of drag pressure.
-
Saltwater Shielded: Constructed from premium stainless steel to prevent rust-pitting, which is the leading cause of spring snapping in offshore reels.
-
Precision Tension: Calibrated to the exact specifications of the Tiagra and TLD-II series to ensure a "true" free-spool.
-
Direct OEM Fit: Guaranteed to fit over the spool shaft and within the pressure plate housing without binding.
